You have to trigger the onchange event yourself after changing the value.
HTML
<input id="myHiddenFiled" type="hidden" onchange="changed()" />

Open in new window

JavaScript
function changed(){
    alert('changed');
}

var hiddenField = document.getElementById('myHiddenFiled');
hiddenField.value = 'new value';
hiddenField.onchange();

Open in new window
